Description

[Detailed description of the invention] This invention relates to a reciprocating electric shaver.

A conventional reciprocating electric shaver is shown in FIG.

That is, 1 is a main body housing which also serves as a grip and houses a battery, a morph, and a transmission drive unit, 2 is a razor head, and 3 is a switch.

In this reciprocating electric razor, the main housing 1 and the head 2 are integrated, so when shaving, you have to change the way you hold the electric razor or rotate your wrist to match the shaving position, making it difficult to use. It had the disadvantage of being bad.

Furthermore, even if the razor head is placed along the skin during shaving, the razor head is fixed to the grip, which makes the curly hair less likely to be raised and the effect of cutting the curly hair to be weak.

For this reason, it is generally necessary to devise ways to improve the efficiency of introducing the curly hair into the blade.

However, when the blade is provided with a hair-raising means, the blade has a complicated shape, which makes it uncomfortable to touch the skin.

Therefore, an object of the present invention is to provide an electric shaver that is easy to use, gives good skin shine, and can easily improve the efficiency of introducing curly hair.

An embodiment of this invention is shown in FIGS. 2 to 4.

That is, in this reciprocating electric shaver, the battery 5 and mokuro storage section 7 of the main body housing 4 are formed into a cylindrical shape with a step 8, and a threaded cylinder 9 is protruded from the center of the bottom surface.

A cylindrical grip 10 is externally fitted into the storage part 7, its open end surface is brought into contact with the step 8, and a stepped hole 11 is formed at the center of the bottom, and the stepped screw 12 is screwed into the threaded cylinder 9 to rotate each other. Connect freely.

A torsion coil spring 13 is passed through the surface of the threaded cylinder 9, and one end thereof is inserted into the bottom of the storage part 7 through a hole 14, and the other end is inserted into the bottom of the grip 10 through a hole 15 formed therein.

In addition, 16 is a vibrator, 17 is a drive part, 18 is an inner cutter frame, 19 is an inner cutter, 20 is an outer cutter frame of the head 2, and 21
is the outer blade.

With this configuration, when using this reciprocating electric shaver, the head 2 can be rotated with respect to the grip 10, and since the head 2 is reciprocating, it is difficult to shave in the longitudinal direction due to the strong resistance against the skin. Rotate perpendicular to the operating direction.

Therefore, the head 2 can be directed in a desired direction without rotating the wrist or changing the grip, improving usability.

In particular, the inclusion of a return spring makes it even more convenient to use.

As described above, since the electric razor of the present invention has a rotation return spring interposed between the grip and the head, the entire razor head can brush up curly hair by rotating the razor head with respect to the grip, and it also feels good on the skin. Moreover, the return spring has the effect that it can be used in a convenient state.
